The new 77-19000 Tubular Radius Arm upgrade kit for the 2019-2024 Ram 2500/3500. These new Radius Arms are heavy-duty and are built to handle the use and abuse demanded out of Ram trucks and serve as critical alignment components correcting the suspension geometry on lifted models. The arms are formed inward allowing for additional clearance and providing even more space for oversized tires. The direct bolt-on design promotes quick and easy installation.
